Suncam

Suncam tells you where the light will be, before you get there. Drop a pin on the map. Suncam draws the exact bearing of sunrise and sunset, the moon's path, and lays out the day: dawn, golden hour, blue hour, dusk. Drag the timeline with your thumb and the sun line sweeps across the map in real time, and you watch the light move over the landscape, hour by hour. THE TERRAIN THAT STEALS YOUR LIGHT A 9:30 PM sunset means nothing if a ridge puts you in shadow at 7. Suncam reads the elevation all around your spot within 20 km and works out when the sun actually disappears. In a valley the gap runs into hours, and no ephemeris table will show it to you. THE SUN'S PATH IN YOUR VIEWFINDER Raise your iPhone: the day's arc overlays the real landscape, coloured by moment of light. You see where the sun will land behind those trees, when it will strike that wall. One tap while aiming at the sun calibrates the compass, and the drawn disc lines up with the real one. THE SUN ON YOUR AXIS Aim at a lighthouse, a summit, a rock arch: Suncam finds the days of the year when the sun rises or sets exactly on that line from your spot. If it never does, it tells you so. THE FULL MOON, RIGHT ON TIME The lunar calendar shows each day's phase and the moonrise time at your spot. Suncam also finds the rare evenings when a nearly full moon rises on the horizon during golden hour: the one moment when moon and landscape expose in the same shot. And the timeline follows you to the end of the night. YOUR SPOTS, ORGANISED Search a harbour, a summit, a beach. One star keeps it, one folder files it. Every spot stays visible on the map, at any zoom. ACCURACY YOU CAN CHECK Sun and moon positions are computed on the device, from the algorithms of Jean Meeus and NOAA. The times were compared against US Naval Observatory ephemerides from the tropics to the Arctic Circle: the difference is measured in seconds. Because everything is computed locally, the app works with no connection. Only the terrain analysis needs one. WHAT YOU PAY 7 days to try everything, then a single purchase. No subscription, no renewal, no account to create. Your spots stay on your iPhone. Built for photographers, Suncam also serves hikers, climbers, gardeners, and anyone who needs to know where the sun will fall.
Don't Swipe Viewer

Ever handed someone your iPhone to show one photo, only for them to start swiping through the rest of your library? Don't Swipe lets you choose exactly which photos and videos they can see. Select up to 50 photos and videos in the app, or share them directly from Apple Photos to Don't Swipe. They can swipe, zoom, and play videos, but only the items you selected. The rest of your photo library stays private. To exit, Don't Swipe requires a two-finger hold followed by Face ID, Touch ID, or your passcode. No account, ads, analytics, or uploads. Your media stays on your device, and temporary viewing copies are deleted after the session. For extra protection, you can also use Don't Swipe with Apple's Guided Access. Show the moment. Not your library.
